What Is JAXP?

This section provides a quick introduction of Java API for XML Processing (JAXP) that included in JDK 1.6.

What is JAXP? JAXP (Java API for XML Processing) is Java API that enables Java applications to parse, transform, validate and query XML documents independent of a particular XML processor implementation. JAXP provides a pluggability layer to enable vendors to provide their own implementations without introducing dependencies in application code. Using this software, application and tool developers can build fully-functional XML-enabled Java applications for e-commerce, application integration, and web publishing.

JAXP specification is maintained as JSR (Java Specification Requests) 206 by JCP (Java Community Process), see https://jcp.org/en/jsr/detail?id=206.

Here is the JAXP version history and related Java Platforms:

JAXP 1.6: Java Platform, Standard Edition 8 and above
JAXP 1.5: Java Platform, Standard Edition 7 and above
JAXP 1.4: Java Platform, Standard Edition 6 and above
JAXP 1.3: Java Platform, Standard Edition 5 and above

JAXP has been included in standard JDK package since JDK 1.4. You don't need to download anything JAR files separately to use JAXP.

JAXP API contains 3 groups of class packages:

1. Java API for XML Processing (JAXP) - The core interface packages.

2. Document Object Model (DOM) - DOM specific packages.

3. Simple API for XML (SAX) - SAX specific packages.

The default implementation classes of JAXP are from the Apache Xerces project.
